PISTON ACOUSTIC GAS BLOWER Russian patent published in 2021 - IPC F04F1/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, in particular to devices for gas injection, and can be used in technological processes associated with heat and mass transfer processes, spraying liquid, pasty and powdery media, preparing suspensions, emulsions and solutions, cleaning contaminated water from solid, liquid and resinous pollution, combustion of solid, liquid and gaseous fuels and ventilation of large premises. The blower contains a working chamber closed at one end by a wall. The piston is installed in the working chamber with possibility of oscillatory movement and has a flare adapter and pipe. In the working chamber, between the wall and the piston, a coaxially located solenoid is installed in a stationary position, made in form of a conductive winding and a core, which is inserted at one end into the hole of the conductive coil of the solenoid, and at the other end is rigidly connected to the piston, spring-loaded by a flexible element. The flexible element is made in form of a bellows located outside the conductive coil of the solenoid and coaxial to it. One end of the bellows is attached to the wall of the working chamber, and the other end is attached to the piston.

EFFECT: energy consumption and metal consumption are reduced, and the design is also simplified.
